Once the materials have been fitted, it is advisable to remove any remaining adhesive and grouting material by using a commercial descaling product designed especially, diluted with water. The descaling product must not remain in contact with the surface to be cleaned for more than 5 minutes.
As a general guideline, powder detergents should not be
used, not wire wool or abrasive materials. Generally a sponge will be sufficient with warm water and liquid neutral soap. Then rinse with plenty of clean water.
